Mix the oats, flour, sugar and coconut in a bowl. Place the golden syrup and butter in a saucepan over low heat and melt.

Mix the bicarbonate of soda with the water and add to the butter mixture. Pour the butter mixture into the dry ingredients and mix well.

Spoon tablespoons of the mixture onto baking trays lined with non-stick baking paper and flatten to about 7cm in diameter, leaving space between each for spreading. Bake for 10 minutes or until a golden brown.

Cool on baking trays for 5 minutes, then transfer to wire racks to cool completely.
